VPS / IDS Issue R1Soft

Known Issue

Server VPS/IDS yang di install R1Soft mengalami beberapa anomali aneh (R1soft Issue) seperti diantaranya :

• High memory saat running backup pada process cdp_io
• Daemon cdp_agent / sbm_agent mati tiba-tiba after/before backup run
• Expected issue di Centos 8.x

Why

• The Ext4 file system is using the “metadata_csum” feature.
• R1soft support have received few reports from customers regarding problems with this feature.

Workaround (need reboot)

< As root user >

# umount /dev/sda3 (/ volume) <You will probably need to boot the system using live image of Linux>
# e2fsck -Df /dev/sda3 (or whatever the device pointer is used to describe this partition after booting into live image)
# tune2fs -O uninit_bg,^metadata_csum /dev/sda3
# e2fsck -Df /dev/sda3
# mount /dev/sda3 / (Or just boot into the actual installation)
